[BACKPORT GDB 14][PATCH] PowerPC: Add support for Power11 options

[Peter Bergner <bergner@linux.ibm.com>]

I'd like to backport the following patch to the GDB 14 release branch.
This has been on trunk for a while and backported to the binutils
2.41 release branch.  Testing of the backport was clean.
Ok for the GDB 14 release branch?  


Peter


PowerPC: Add support for Power11 options

binutils/
	* doc/binutils.texi (PowerPC -M option): Mention power11 and pwr11.

gas/
	* config/tc-ppc.c: (md_show_usage): Mention -mpower11 and -mpwr11.
	* doc/c-ppc.texi: Likewise.

opcodes/
	* ppc-dis.c (ppc_opts): Add "power11" and "pwr11" entries.
	(powerpc_init_dialect): Default to "power11".

(cherry picked from commit 4199cf1e152daab0460f08cc7dbd1f727ac3e4cc)
